The libutf8proc package prior to version 2.1.1-3 had an incorrect soname link. This has been fixed in 2.1.1-3, so the upgrade will need to overwrite the untracked soname link created by ldconfig. If you get an error
libutf8proc: /usr/lib/libutf8proc.so.2 exists in filesystem
when updating, use
pacman -Suy --overwrite usr/lib/libutf8proc.so.2
to perform the upgrade.
Due to the SONAME of
/usr/lib/libmozjs-52.so not matching its file name, ldconfig created an untracked file
/usr/lib/libmozjs-52.so.0. This is now fixed and both files are present in the package.
To pass the upgrade, remove
/usr/lib/libmozjs-52.so.0 prior to upgrading.
The new version of glibc removes support for NIS and NIS+. The default
/etc/nsswitch.conf file provided by
filesystem package already
reflects this change. Please make sure to merge pacnew file if it exists
prior to upgrade.
NIS functionality can still be enabled by installing
package. There is no replacement for NIS+ in the official repositories.
pam 1.3.0-2 no longer ships pam_unix2 module and
compatibility symlinks. Before upgrading, review PAM configuration files
/etc/pam.d directory and replace removed modules with
pam_unix.so. Users of pam_unix2 should also reset their passwords
The zita-resampler 1.6.0-1 package was missing a library symlink that has been readded in 1.6.0-2. If you installed 1.6.0-1, ldconfig would have created this symlink at install time, and it will conflict with the one included in 1.6.0-2. In that case, remove /usr/lib/libzita-resampler.so.1 manually before updating.
Following 9 months of deprecation period, support for the i686
architecture effectively ends today. By the end of November, i686
packages will be removed from our mirrors and later from the packages
archive. The [multilib] repository is not affected.
For users unable to upgrade their hardware to x86_64, an alternative is
a community maintained fork named Arch Linux 32. See their website
for details on migrating existing installations.
